Hello, looking for some info from volatility etf traders..
I'm experimenting with a volatility algo that sometimes makes considerable short positions in volatility etfs (VXX, XIV for example)
I'm getting very good results from backtesting but I have not traded this with actual money so are there pitfalls in execution side that quantopian is not able to model?
(I'm aware of the volatility risks associated with trading volatility so no need to inform me about algo risks, this question is about execution risks that quantopian is maybe not able to model correctly)
